NASA’s Opportunity Discovers Geological Mystery on Mars
Circular articles accumulated at an outcrop Opportunity arrived at last week contrast in more ways than one from iron-rich spherules nicknamed “blueberries” the meanderer found at its arrival site in mid 2004 and at numerous different areas to date.

Opportunity is examining an outcrop called Kirkwood in the Cape York section of the western edge of Endeavor Crater. The circles measure as much as one-eighth of an inch (3 millimeters) in distance across. The examination is as yet primer, however it demonstrates that these circles don’t have the high iron substance of Martian blueberries.
“This is one of the most phenomenal pictures from the entire mission,” said Opportunity’s main specialist, Steve Squyres of Cornell University in Ithaca, N.Y. “Kirkwood is stuffed with a thick gathering of these little round objects. Obviously, we promptly thought about the blueberries, yet this is something other than what’s expected. We never have seen such a thick aggregation of spherules in a stone outcrop on Mars.”
The Martian blueberries found somewhere else by Opportunity are solidifications shaped by activity of mineral-loaded water inside rocks, proof of a wet climate on early Mars. Solidifications result when minerals hasten out of water to turn out to be hard masses inside sedimentary rocks. A considerable lot of the Kirkwood circles are broken and dissolved by the breeze. Where wind has to some extent scratched them away, a concentric design is apparent.
Opportunity utilized the minuscule imager on its arm to intently take a gander at Kirkwood. Analysts checked the circles’ creation by utilizing an instrument called the Alpha Particle X-Ray Spectrometer on Opportunity’s arm.
“They appear to be crunchy outwardly, and milder in the center,” Squyres said. “They are distinctive in focus. They are diverse in structure. They are distinctive in structure. They are diverse in conveyance. In this way, we have a brilliant geographical riddle before us. We have different working speculations, and we have no most loved theory as of now. It will require a significant stretch of time to figure out this, so what to would now is keep an open care and let the stones communicate everything.”
Simply past Kirkwood lies another science target region for Opportunity. The area is a broad pale-conditioned outcrop in a space of Cape York where perceptions from circle have identified indications of dirt minerals. That might be the meanderer’s next concentrate available after Kirkwood. Four years prior, Opportunity left Victoria Crater, which it had researched for a very long time, to arrive at various kinds of topographical proof at the edge of the a lot bigger Endeavor Crater.
The meanderer’s energy levels are positive for the examinations. Spring equinox comes this month to Mars’ southern side of the equator, so the measure of daylight for sun based power will keep expanding for quite a long time.
“The meanderer is in awesome wellbeing thinking about its 8-1/2 years of difficult work on the outer layer of Mars,” said Mars Exploration Rover Project Manager John Callas of NASA’s Jet Propulsion Laboratory in Pasadena, California. “Energy creation levels are practically identical to what they were a full Martian year prior, and we are anticipating useful spring and summer periods of investigation.”
NASA dispatched the Mars meanderers Spirit and Opportunity in the mid year of 2003, and both finished their three-month prime missions in April 2004. They proceeded with reward, broadened missions for a really long time. Soul completed the process of speaking with Earth in March 2010. The wanderers have made significant revelations about wet conditions on old Mars that might have been good for supporting microbial life.
